Account blocked and not being verified

I have previously verified my account, but now when I login my account, this error message occurs "This account has been blocked. Please verify your account at https://katalon.com. See instructions at https://docs.katalon.com/katalon-studio/docs/troubleshoot-activation-problems.html."

After reading the document related to this issue, it said to verify the account on this link: https://katalon.com. But when I login to verify the account, the verify button/option is not available. What should I do now?
